Case report demonstrates unique vascular anatomy impacting surgical approach in colon cancer patients, indicating the need for preoperative imaging.
INTRODUCTION: Anatomical vascular variations are frequently observed in the right colon. The ileocolic vein (ICV) typically drains directly into the superior mesenteric vein (SMV). When vascular anomalies are present, surgical procedures often differ from standard techniques, which frequently increases the difficulty of the operation. Therefore, preoperative confirmation of vascular variations is essential. Here, we present a case of ascending colon cancer in which a rare variation in the ICV was diagnosed preoperatively.
